These are the 64 startups unveiled at Y Combinator W18 Demo Day 2

Microbiome therapeutics, Photoshop for augmented reality, and cancer treatments were some of the ideas presented at Day 2 of startup accelerator Y Combinator’s Winter 2018 Demo Day. YC is increasingly using its massive class size (141 startups this time around) to fund especially risky frontier technology and biotech moonshots, while tempering the portfolio with more predictable enterprise companies. Investors say that valuations for post-Demo Day raises have risen steeply recently. Some speculate that people who made a fortune on cryptocurrency are trying to invest their returns elsewhere, driving up demand for YC startups. The accelerator still admits many international copycats of U.S. successes, and YC is also repeating itself a bit. The Podcast App pitched the exact same product and strategy as Breaker, which debuted at YC exactly a year ago. But there were plenty of ambitious and unique businesses unveiled today on the Mountain View Computer History Museum stage, and the room was — as always — packed with a who’s who of tech investors. Check out our coverage of all 64 startups that launched on the record yesterday, plus our picks for the top 7 companies from yesterday. (Tomorrow morning we’ll have our favorites from today.) Here are the 60+ startups that launched at YC’s Winter 2018 Demo Day 2: Callisto Callisto is a sexual misconduct reporting software built for victims. The company’s product works by asking people who are looking to report a perpetrator to give certain unique identifiers, like a LinkedIn profile or phone number. If two victims name the same perpetrator, they are put in touch with each other and then with with an “options counselor,” a lawyer who can give them options on how to proceed in handling the situation. The company says that victims that visit Callisto’s website are 5x more likely to take action. They’ve started by rolling out their product on college campuses and are now taking donation from investors to roll out the service to the startup community. Bump Bump is a peer-to-peer streetwear marketplace. It’s the “eBay for Generation Z.” They’ve been rapidly building an online community, and achieved $25,000 revenue on $430,000 GMV already in the month of March. They claim to be profitable and also have a user community that’s engaged. Bump says that 600,000 messages are sent be users for every week. They believe they can eventually move beyond streetwear.
